High temperature culture technology of crayfish

It is not easy for farmers in hot summer, with the continuous rise of summer temperature in China in recent years, the importance of high-temperature breeding technology is becoming more and more important, especially crayfish, which is the product of partial diving culture. The following pro-agricultural network will take you to understand the relevant issues in this area.

1. Management of aquatic plants

Crayfish culture will basically be mixed with aquatic plants, because this will bring a high-quality growth environment for crayfish. When breeding in summer, we must control the growth size of aquatic plants, too high will affect the water quality, too small is not conducive to protect the crayfish from the high temperature. So while ensuring the growth of aquatic plants every day, it is necessary to sort out those that are too large. Aquatic plants must show a dot distribution in order to maximize the crayfish for the summer.

2. Water quality control

The requirement for water quality in summer is extremely high, and low water quality can easily lead to mass death of crayfish. First of all, it is necessary to ensure the fluidity of the water quality, as the water for raising crayfish is not very deep, so if the static water temperature rises easily in a very hot environment, the oxygen content will be seriously reduced. Secondly, the water level of aquaculture should be properly deepened in summer to avoid direct sunlight on the bottom. Finally, some algae can be cultured underwater to improve the current water quality, and it can also provide a better feeding environment for crayfish.

3. Feeding and management

The feeding time of crayfish in summer must be selected, generally only twice. When the temperature is low in the morning and evening and the weather is hot at noon, the crayfish do not have a high appetite and the feeding effect is not good. The appearance of feeding is longer than that of other time periods, and the amount of each feeding should be less, so as to avoid waste, and it is better to control the feeding time at about one and a half hours. It is better to feed a diet with a higher protein content, which helps to improve the high temperature resistance of crayfish.

4. Daily management

Crayfish like to stay in the diving position on summer nights, so we should patrol the ponds more to avoid some enemy creatures preying on crayfish. The second is to prevent crayfish from escaping on a large scale at night. During the day, the residue on the bottom of the pool should be cleaned in time. The residue on the bottom of the pool in summer is easy to deteriorate, which can easily cause crayfish to infect some diseases and damage the water quality. We must pay attention to this point.

The above is the way of crayfish breeding at high temperature. Crayfish are more active when the sun goes down and behind in summer. We need to strengthen management during this period, and feed more food appropriately. The ability of crayfish to drill holes and escape is recognized as good, so farmers should not take the maintenance of their breeding grounds lightly.
